The Timney is, IMO, well worth the $120+/-.

For me, the biggest negative about the RAR-Predators is that the stock doesn't fit me as well as I'd like and the only option that I'm aware of are a few different styles from Boyds. I find it more than a little annoying that Boyds is selling a steel trigger guard for their RAR stocks for $30+/- above the price of the stock and the parts kit with a crappy plastic trigger guard that comes with it.
